This patch try to introduce the rwlock and split the read/write to
unit_root tree and unit_cache with rwlock instead of the mutex to
increase CPU efficiency. In the get_gfc_unit function, the percentage
to step into the insert_unit function is around 30%, in most instances,
we can get the unit in the phase of reading the unit_cache or unit_root
tree. So split the read/write phase by rwlock would be an approach to
make it more parallel.
BTW, the IPC metrics can gain around 9x in our test
server with 220 cores. The benchmark we used is

This patch enables the use of mixed-types for simd clones for AArch64, adds
aarch64 as a target_vect_simd_clones and corrects the way the simdlen is chosen
for non-specified simdlen clauses according to the 'Vector Function Application
Binary Interface Specification for AArch64'.
Additionally this patch also restricts combinations of simdlen and
return/argument types that map to vectors larger than 128 bits as we currently
do not have a way to represent these types in a way that is consistent
internally and externally.
gcc/ChangeLog:
* config/aarch64/aarch64.cc (lane_size): New function.

and reject combination of simdlen and types that lead to vectors larger than 128bits.

This commit adds -fopenmp-allocators which enables support for
'omp allocators' and 'omp allocate' that are associated with a Fortran
allocate-stmt. If such a construct is encountered, an error is shown,
unless the -fopenmp-allocators flag is present.
With -fopenmp -fopenmp-allocators, those constructs get turned into
GOMP_alloc allocations, while -fopenmp-allocators (also without -fopenmp)
ensures deallocation and reallocation (via intrinsic assignments) are
properly directed to GOMP_free/omp_realloc - while normal Fortran
allocations are processed by free/realloc.
In order to distinguish a 'malloc'ed from a 'GOMP_alloc'ed memory, the
version field of the Fortran array discriptor is (mis)used: 0 indicates
the normal Fortran allocation while 1 denotes GOMP_alloc. For scalars,
there is record keeping in libgomp: GOMP_add_alloc(ptr) will add the
pointer address to a splay_tree while GOMP_is_alloc(ptr) will return
true it was previously added but also removes it from the list.
Besides Fortran FE work, BUILT_IN_GOMP_REALLOC is no part of
omp-builtins.def and libgomp gains the mentioned two new function.

This implements the OpenMP low-latency memory allocator for AMD GCN using the
small per-team LDS memory (Local Data Store).
Since addresses can now refer to LDS space, the "Global" address space is
no-longer compatible. This patch therefore switches the backend to use
entirely "Flat" addressing (which supports both memories). A future patch
will re-enable "global" instructions for cases where it is known to be safe
to do so.

* config/gcn/gcn-builtins.def (DISPATCH_PTR): New built-in.

addressing.

The NVPTX low latency memory is not accessible outside the team that allocates
it, and therefore should be unavailable for allocators with the access trait
"all". This change means that the omp_low_lat_mem_alloc predefined
allocator no longer works (but omp_cgroup_mem_alloc still does).

This patch adds support for allocating low-latency ".shared" memory on
NVPTX GPU device, via the omp_low_lat_mem_space and omp_alloc. The memory
can be allocated, reallocated, and freed using a basic but fast algorithm,
is thread safe and the size of the low-latency heap can be configured using
the GOMP_NVPTX_LOWLAT_POOL environment variable.
The use of the PTX dynamic_smem_size feature means that low-latency allocator
will not work with the PTX 3.1 multilib.
For now, the omp_low_lat_mem_alloc allocator also works, but that will change
when I implement the access traits.

These test cases being 'dg-skip-if [...] { ! amdgcn-*-* }' meant they were
only ever considered for 'amdgcn-*-*' target -- that is, GCN *target*, not
GCN *offload target*, what is intended to be tested here, but for which they
thus always were UNSUPPORTED. Use the same style of 'dg-[...]' directives
as for the nvptx offloading test cases, 'libgomp.c/declare-variant-3*.c'.

Add the new CDNA register file. We don't support any of the specialized

register pressure without spilling to stack.

The patch 'openmp: Add support for the 'indirect' clause in C/C++'
introduced a new file target-indirect.c into the Makefile sources,
but that file was only present in config/linux/ and config/accel/,
so targets that are not Linux-based or GPU accelerators will not
pick it up and fail to build.
This is fixed by making the version in config/linux/ the default by
moving it into the base directory of libgomp.

This adds support for the 'indirect' clause in the 'declare target'
directive. Functions declared as indirect may be called via function
pointers passed from the host in offloaded code.
Virtual calls to member functions via the object pointer in C++ are
currently not supported in target regions.

This patch implements the 'self' clause for compute constructs: parallel,
kernels, and serial. This clause conditionally uses the local device
(the host mult-core CPU) as the executing device of the compute region.
The actual implementation of the "local device" device type inside libgomp
(presumably using pthreads) is still not yet completed, so the libgomp
side is still implemented the exact same as host-fallback mode. (so as of now,
it essentially behaves like the 'if' clause with the condition inverted)

Recent Darwin versions place contraints on the use of run paths
specified in environment variables. This breaks some assumptions
in the GCC build.
This change allows the user to configure a Darwin build to use
'@rpath/libraryname.dylib' in library names and then to add an
embedded runpath to executables (and libraries with dependents).
The embedded runpath is added by default unless the user adds
'-nodefaultrpaths' to the link line.
For an installed compiler, it means that any executable built with
that compiler will reference the runtimes installed with the
compiler (equivalent to hard-coding the library path into the name
of the library).
During build-time configurations any "-B" entries will be added to
the runpath thus the newly-built libraries will be found by exes.
Since the install name is set in libtool, that decision needs to be
available here (but might also cause dependent ones in Makefiles,
so we need to export a conditional).
This facility is not available for Darwin 8 or earlier, however the
existing environment variable runpath does work there.
We default this on for systems where the external DYLD_LIBRARY_PATH
does not work and off for Darwin 8 or earlier. For systems that can
use either method, if the value is unset, we use the default (which
is currently DYLD_LIBRARY_PATH).
ChangeLog:
* configure: Regenerate.
* configure.ac: Do not add default runpaths to GCC exes
when we are building -static-libstdc++/-static-libgcc (the
default).

enable flag to alter Darwin libraries to use @rpath names.

Accept the architecture configure option and resolve build failures. This is
enough to build binaries, but I've not got a device to test it on, so there
are probably runtime issues to fix. The cache control instructions might be
unsafe (or too conservative), and the kernel metadata might be off. Vector
reductions will need to be reworked for RDNA2. In principle, it would be
better to use wavefrontsize32 for this architecture, but that would mean
switching everything to allow SImode masks, so wavefrontsize64 it is.
The multilib is not included in the default configuration so either configure
--with-arch=gfx1030 or include it in --with-multilib-list=gfx1030,....
The majority of this patch has no effect on other devices, but changing from
using scalar writes for the exit value to vector writes means we don't need
the scalar cache write-back instruction anywhere (which doesn't exist in RDNA2).

The omp_lock_hint_* parameters were deprecated in favor of
omp_sync_hint_*. While omp.h contained deprecation markers for those,
the omp_lib module only contained them for omp_{g,s}_nested.
Note: The -Wdeprecated-declarations warning will only become active once
openmp_version / _OPENMP is bumped from 201511 (4.5) to 201811 (5.0).
libgomp/ChangeLog:
* omp_lib.f90.in: Tag omp_lock_hint_* as being deprecated when
_OPENMP >= 201811.

-fopenacc/-fopenmp update
The OpenACC specification does not mention the '!$ ' sentinel for conditional
compilation and the feature was removed in r11-5572-g1d6f6ac693a860
for PR fortran/98011; update libgomp.texi for this and update a leftover
comment. - Additionally, some other updates are done as well.
libgomp/
* libgomp.texi (Enabling OpenMP): Update for C/C++ attributes;
improve wording especially for Fortran; mention -fopenmp-simd.
(Enabling OpenACC): Minor cleanup; remove conditional compilation
sentinel.
gcc/
* doc/invoke.texi (-fopenacc, -fopenmp, -fopenmp-simd): Use @samp not
@code; document more completely the supported Fortran sentinels.
gcc/fortran
* scanner.cc (skip_free_comments, skip_fixed_comments): Remove
leftover 'OpenACC' from comments about OpenMP's conditional
compilation sentinel.

None of the ACC_* env vars was documented; in particular, the valid valids
for ACC_DEVICE_TYPE found to be lacking as those are not document in the
OpenACC spec.
GCC_ACC_NOTIFY was removed as I failed to find any traces of it but the
addition to the documentation in commit r6-6185-gcdf6119dad04dd
("libgomp.texi: Updates for OpenACC."). It seems to be planned as GCC
version of the ACC_NOTIFY env var used by another compiler for offloading
debugging.
libgomp/
* libgomp.texi (ACC_DEVICE_TYPE, ACC_DEVICE_NUM, ACC_PROFLIB):
Actually document what the function does.
(GCC_ACC_NOTIFY): Remove unused env var.

This commit completes the documentation of the OpenMP memory-management
routines, except for the unimplemented TR11 additions. It also makes clear
in the 'Memory allocation' section of the 'OpenMP-Implementation Specifics'
chapter under which condition OpenMP managed memory/allocators are used.
libgomp/ChangeLog:
* libgomp.texi: Fix some typos.
(Memory Management Routines): Document remaining 5.x routines.
(Memory allocation): Make clear when the section applies.
